In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vector dataset. More concretely, we present algorithms for solving a spatia

Infestation of gregarines from genus Nematopsis in Pacific white shrimp Litopenaeus vannamei is commonly associated with a decrease in production and low weight, as well as a possible predisposition to viral infections. The goal of our past research

In this paper, we present two algorithms to obtain the convex hull of a set of points that are stored in the compact data structure called $$k^2$$ - $$tree$$ . This problem consists in given a set of points P in the Euclidean space obtaining the smal

Binary relations are commonly used to represent relationships between real-world objects. Classical representations for binary relations can be very space-consuming when the set of elements is large. In these cases, compressed representations, such a

In the context of Big Data scenarios, the presence of extensive static datasets is not uncommon. To facilitate efficient queries on such datasets, the utilization of multiple indexes, such as the Kd-tree, becomes imperative. The current scale of mana
